The coefficient of H2 SO4 on balancing ...

The coefficient of `H_2 SO_4` on balancing the following equation is ...........
` K_2 Cr_2 O_7 +H_2 SO_4 +KI to K_2 SO_4 +Cr_2 (SO_4)_3 +H_2 O +I_2`

Text Solution

Verified by Experts

The correct Answer is:
7
The balanced equation is
`K_2 Cr_2 O_7 + 7 H_2 SO_4 + 6KI to 4 K_2 SO_4 + Cr_2 SO_4 + Cr_2 (SO_4)_3 + 7 _2 O + 3I_2 `
